"Tomorrow, sell your camel and buy a horse. Camels are traitorous: they walk thousands of paces and they never seem to tire. Then suddenly, they kneel and die. But horses tire bit by bit. You always know how much you can ask of them, and when it is that they are about to die."

This quality of pastness is an illusion. The truth is, as Jacoby and many followers have shown, that the name David Stenbill will look more familiar when you see it because you will see it more clearly.

The paradox is that in our zeal to improve the predictability of software development, we have institutionalized practices that have had the opposite effect. We create a plan, and then we act on that plan as if it embodies an accurate prediction of the future.

Paradoxes are the opposite of contradictions. Contradictions shut themselves down, but paradoxes keep themselves going, because every time you acknowledge the truth of one side you're going to get caught from behind by the truth on the other side.

The practice of all the arts is for the purpose of clearing away what is on your mind. In the beginning, you do not know anything, so paradoxically you do not have any questions on your mind. Then, when you get into studies, there is something on your mind and you are obstructed by that. This makes everything difficult to do.

Those we know as masters are dedicated to the fundamentals of their calling. They are zealots of practice, connoisseurs of the small, incremental step. At the same time - and here's the paradox - these people, these masters, are precisely the ones who are likely to challenge previous limits.

Usually when you listen to some statement, you hear it as a kind of echo of yourself.
You are actually listening to your own opinion.
If it agrees with your opinion you may accept it, but if it does not, you will reject it or you may not even really hear it.

It's sometimes hard to know when someone is listening - rather than merely waiting to seize control of the conversation.
One way everyone knew Mack wasn't listening was by noticing how seldom he allowed other people to finish what they were saying.

He learned more from the river than Vasudeva could teach him. He learned from it continually. Above all, he learned from it how to listen, to listen with a still heart, with a waiting, open soul, without passion, without desire, without judgement, without opinions.
